Fan is making a constant noise

  • Ray Seb Nov 02, 2012

    thx for the help I cleaned the dust and found what looks like the problem fan. It is situated on the Video graphics board(?) in a very thin space within a black plastic covering. It looked very dusty, so I have to remove it and give a good cleaning. The suggestion to clean and blow out the dust has made a good difference.

How to Reduce the Noise of Your CPU Fan

The CPU fan is what keeps the processor of your computer cool while the machine is running. A noisy fan on the CPU can be very annoying for users of the computer. However, it can also be a sign of a dangerous problem in your system. If the CPU fan is making noise, it is probably not running at full capacity to cool the processor, which leaves your computer open to problems involving overheating of the processor. An overheated processor can be permanently damaged.
Step 1

Unplug the computer from the wall. Remove all devices from the back of the computer and move them away from the area where you will be working. Either wear an anti-static wristband or discharge any static by touching a metal part of the computer case.
Step 2

Remove the screws from the back of the computer case with a screwdriver. Pull the sides of the case off and set them aside. Lay the computer on its side so that you can easily see the motherboard and all parts connected to it. Locate the CPU fan; it will look similar to the image in the introduction.
Step 3

Ensure that no cables are hanging low and touching the blades of the CPU fan. Move any cables or other parts that could be hitting the blades of the fan causing noise. Tuck these cables and wires into an area where they cannot interfere with the CPU fan.
Step 4

Use a cotton swab to remove any dust that you can from the blades of the CPU fan. Don't use any harsh solvents or other cleaners that could drip down and damage the processor through the fan.
Step 5

Spray the compressed air into the fan to move the loose dust away from the processor fan. Move the dust into an empty section of the case with the canned air. Don't spray the air too hard or else you can spread the dust into other places in the computer.
Step 6

Use the vacuum cleaner to vacuum up the dust that you moved away from the CPU. Place a crevice tool or other attachment onto the hose to reduce the size of the opening and help ensure that you only remove dust.
Step 7

Replace the computer case. Plug the computer and all devices back in. Boot up the computer and check for reduced CPU fan noise.

SOURCE: acer m5100 desktop fan is making noise

Hi:
Often, just dust can make fans noisy. You can unplug everything, take the side cover off of your tower, and blow it out with a can of the air duster you can buy at a computer store, paying close attention to the fans. If you are not comfortable with this, a local shop should be able to clean it up for you for not a lot of cash, and if a fan is really bad, they could identify which one it is for you too.

SOURCE: My PC desktop is making a clicking noise

Assuming the 'clicks' are heard when you're on the net...it could be a page in the background updating its 'ad' or auto 'clicking' to another page (within the main page on a different frame). This happen alot on hotmail pages ads using 'Flash'.

You can turn the volume off while surfing until you need to listen to something & turn your volume back on. (I do)

Hope this throws some light on the issue
Good Luck!

SOURCE: My processor is making a strange noise.The fans

Processor is clean?

Hmmm, are you sure you aren't referring to the Heatsink, sitting on top of the Processor's case?

One example of a typical Heatsink/Fan combo,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3451342&CatId=493

[Typical construction of a Heatsink is a flat plate of metal, with tall, thin fins protruding from it.

The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb the heat from the plate, whereupon the fins radiate the heat away.

A Processor isn't the only hardware component inside a personal computer, that utilizes a Heatsink.

A Heatsink is also utilized inside a Power Supply, (Usually more than one Heatsink), and on graphics cards.
Some high-performance ram memory modules, ('Stick'), may also use a type of Heatsink. (Heat Spreader ]

In your reference, "The fans are clean, and so is the Processor", I hope this isn't an actual reference that the top of the Processor's case is clean.

There Absolutely MUST be thermal paste, used in-between the top of the Processor's case, and the bottom of the Heatsink.

The top of a Processor's case, and the bottom of a Heatsink are not perfectly smooth. A microscopic view would reveal, 'Hills, Valleys, and Pit holes'

These minute imperfections create air pockets, in-between the top of the Processor's case, and the bottom of the Heatsink.

Air is an Insulator, not a Conductor.

Thermal paste fills these imperfections, and is an excellent conductor.
Conducts heat from the top of the Processor's case, to the bottom of the Heatsink.

If your Processor has a thermal pad, (Usually whitish in color, and looks just like the description. A flat Pad), suggest you take it off, and throw it at the cat.

Thermal pads are Junk!

Thermal paste, with a one Processor application, averages around $5.
NEVER run a Processor without thermal paste, and ensure that the top of the Processor's case, and the bottom of the Heatsink, are Perfectly clean.

(Computer unplugged from power, Anti-Static Precautions observed. A Processor is the MOST susceptible hardware component in a computer, to Static shock)

I use an old credit card to scrape the old thermal paste from the Processor, and Heatsink. It's plastic so it won't scratch, nor transfer Static electricity.

I then follow with Q-tips dipped in Isopropyl Alcohol.
91 percent, (91%), alcohol is best. 70 percent will do in a pinch.

I advise not using 50/50. (91 percent alcohol, 9 percent water. 70 percent alcohol, 30 percent water, and so on)

Isopropyl Alcohol is also known as Rubbing Alcohol.

[CAUTION!!
Isopropyl Alcohol is Extremely Flammable!
Use in a WELL ventilated room with no sparks, or flames present ]

It may take a few Q-tips, as the thermal paste residue may be a sticky mess.
HAS to be Thoroughly clean, before applying new, fresh thermal paste.

Correct method for applying thermal paste, (Also referred to as thermal grease),

http://www.hardwaresecrets.com/article/274



Ensure that the Heatsink is sitting FLAT on top of the Processor.
Slightly tilted will NOT work.

It is for this reason I dismount the motherboard from the computer case, and from a side view, look across at the mounting of the Heatsink, to the top of the Processor's case.

No daylight must be showing in-between the top of the Processor's case, and the bottom of the Heatsink.
The Heatsink must be sitting perfectly flat, on the top of the Processor's case.

The only time I have heard of a Processor making a noise, is when it is close to failing. (Quit, Die, Kaput)
The noise may be Taps, or a french(?) retreat song, that escapes me at the moment.
(Perhaps it's a song from Bach, or Trachosky, or Mozart)

Some computers use a computer case fan in the front, to push air through a plastic shroud, which encases the Heatsink.

Most computers use a Fan on top of the Heatsink.

In this case, are you sure the wires that provide power to the Processor fan, aren't being hit by the Processor fan blades?

Also, have you checked the Processor fan for bad bearings?

Gently lift up on one side of the Processor's fan blades.
Does the fan seem tight in the bearings, or loose?

If the bearings are bad, it will allow the fan's center hub to tilt to one side, and scrape.

Gigabyte H55M USB3 Buzzing/Beeping problem.


Hello here is the homepage.

http://www.gigabyte.com/products/product-page.aspx?pid=3444#dl

The most common problem is a fan that's failing, or a wire which is hitting the fan blades. There are usually 2 fans: one for the power supply and one for the CPU. If one of these fails completely, its dangerous -- the computer can overheat and basically burn up.

Another possibility is a failing hard drive (the bearings can make noise).
This could also be the graphic card fan failing, or the powersupply fan
( Bad bearings )
If so, it must be renewed.
Try also to blow the case out for dust, with compressed air. ( if any )
Especialy the cpu fan.

Good luck

Constant grinding noise


It sounds like you have a fan with a bunch of gunk on it. Get a can of compressed air and clean out all the vents and fans. Also, take a close look at your video card's fan. It might be the culprit. Many times when they are about to die they make a lot of noise.

Katherine,

Many times when a desktop is making a strange buzzing noise - it is due to a fan malfunction of some sort. Other reasons include a power supply that is faulty or possibly a bad internal speaker.

I would first check the fan(s) for the computer. Start by turning the computer off all of the way. Next, unplug the cords from the unit. You'll need to isolate just the computer tower itself. Next, you'll want to get some compressed air or a vaccuum and gently clean out the areas where the system case fan vents are. If you know how to open the case for your desktop, it wouldn't be a bad idea to make a quick visual check inside of the case for things that may be caught in the fans. Some desktops open via screws on the back plane, and some open with a pull tab/lever.

If cleaning out the dust doesn't resolve the buzzing noise - then you'll need to make sure that the noise is not part of the electronics. If you are hearing an actual electrical buzz and not a speaker or fan noise, then there is likely a larger problem with the computer. In that case - I would take the computer to a certified professional for diagnosis.

Another culprit of buzzing noise may be a CD/DVD drive with a disk stuck in it. Make sure that you have ejected the drive to ensure no disk is stuck in the drive.

I hope this information helps!

Our fan is constantly running now for the last last 3 days when our computer is on. We have the computer on all day and shut it down at night. It is louder than normal. Why is this and can it be fixed. ...


Its not a problem if you have the computer running all day long. Get an additional fan for your computer. An additional fan will reduce the noise as more fans running at low speed produce low sound that a single fan at high speeds. Make sure that the CPU is free from dust. More the DUST, higher the heat and higher the noise.

Desktop computer fan runs constantly


Hi,

Desktop fans do run constantly, you cannot avoid this.

The reason they get loud is because there will be a build up of dust on the fan blades.

To rectify this problem turn off the computer and remove the power cord from the rear. Then you need to remove the side panel from the base unit to expose the motherboard.

You will see that inside the case it is full of dust. Look at the CPU fan (the fan on the motherboard) also take notice of any case fans too, they are at the back.

To clean the fans and the case you can use a clean dry paintbrush or compressed air.

Once the inside of the case is cleaned you will see a noticeable drop in noise.


Regards.

Compac Presario F700 makes constant humming noise


Sounds like its the fan . The more demand you place on the system makes it run hotter so the fan speed automatically increases to compensate

ASUS Lap top computer, 2 months old' makes loud fan type noises at each start up.


Hi

Its normal for a laptop computer or a desktop computer to spin its fans at maximum speed during start up - its part of the power on self test.

If the fan is very loud like on this video the sound is very bad -


that would be a bad fan, constant bad noise. but if your fan only makes noise in start up, its normal.

your warranty should cover the replacement of the fan if its bad.

Tower fan runs fast without stopping


either your computer is running too hot (clean it out physically, or clean out viruses) OR the fan is failing, and it sounds louder and faster cause the bad fan bearings are making that noise.
